NOTE:




Rationale:

The need of today’s manufacturing industrial world is based on best quality & precision

oriented shorter manufacturing cycle time .To satisfy this need the use of CAD/CAM &

automation is inevitable .To satisfy industrial need, diploma engineer should be able to cope

with CAD/CAM technology. With this intention this subject is introduced in the curriculum.

The prerequisites of this subject have been introduced in earlier subjects such as engineering

graphics, engineering drawing & mechanical engineering drawing.

Objectives:

Student should be able to:

1. Understand the fundamentals & use CAD.

2. Conceptualize drafting and modeling in CAD.

3. Prepare CNC part programming.

4. Operate CNC machines.

5. Conceptualize automation and FMS.
